Lian-Li HPC-600 power supply

Flat black is the finish here. The only cover on the casing is the silverish
Lian Li logo at the center of the wire fan grill. A 120mm fan draws air into
the power supply from the internals of the system. The only exit is out the
rear, where the grill offers low resistance due to the ample spacing of the
mesh. A simple wire grill protects the fan from cables or prying fingers while
providing a low resistance to the airflow.

This is first PSU we've seen whose primary ATX and 2x12V cables are both detachable.
The need for these cables to be detachable is somewhat questionable, as they
always need to be used. An extra break in the cable means another point of potential
voltage drop.

The ATX pass-through connector is an interesting feature. It allows
a second power supply to be linked to the HPC-600 (or 500) and be turned on
/ off with the same power switch. That's about all the manual states; there
is no information about how the components should be wired up to the PSUs in
such a setup. For extreme gamers, this may be a superior solution than one of
those kilowatt PSUs. The HPC's 440W maximum 12V power capacity should be enough
for a current CPU and two high power video cards. Any HDDs and other peripherals
could be driven by a secondary, less highly rated PSU, perhaps a 300W unit,
which would be enough for, say, even a dozen HDDs and a couple of optical drives.
It also allows a step-by-step upgrade of power as needed... for example, if
a second high power video card added to the system leaves the original PSU no
longer adequate to power everything. Lian Li really should provide more information
about how best to use this feature, however.
